Analysis on Stereo Mapping Coverage Ability of Agile Satellite
摘要
Abstract
The coverage ability of agile satellite only depends on mapping strip length when swath is determined.According to the stereo mapping process of agile satellite,the general equation of stereo mapping strip length based circular earth model and satellite ground track is deduced,the minimum maneuver ability requirement of agile satellite for stereo mapping is analyzed,and the general equations of attitude maneuver ability requirement for stereo mapping strip length are de duced.Based on typical attitude maneuver ability of some satellite,one application is analyzed,and the effective rules of orbital altitude,preset pitch angle and stereo mapping angel number are obtained.Simulation results show that the increase of orbital altitude and preset pitch angle will result in the increase of stereo mapping strip length with the same other conditions,and the strip length of double-view stereo mapping is longer than three-view stereo mapping.The analysis method and the formula in this paper can provide a reference for system analysis and design of agile satellite.关键词
